![]() If (!bme.begin(0x76)) 2) Description of major parts in the BME280 codeĪdafruit_BME280 bme – Creates the bme object of type Adafruit_BME280. * Use the sea level pressure at your location */ It is always a good practice to connect GND pins first.ĥ) You can find the BME280 working examples in the path given below Step 3: I2C Arduino Code for BME280 sensor 1) Copy the following code in an empty sketch to read the sensor values in a loop #include "Wire.h" Take a jumper (Dupont cable) and connect one end to the GND pin of the Arduino.Ĭonnect the other end of the jumper to the GND pin of the BME280 sensor board. Step 1: Wiring Arduino and the BME280 Board 1) Connect GND of both Arduino UNO and BME280 sensors The following steps will take you through a step-by-step connection guide to complete this project. I will highlight the pin details and the connections first. Step-By-Step Instructions To Connect BME280 To Arduino Hence, this feature helps you to increase the battery life of the product. Connect this to Arduino GND pinĭid you know that humidity sensor and pressure sensor can be individually enabled or disabled?įor example, if you only need to measure the temperature and humidity, then you can disable the pressure sensor.ĭisabling the unwanted sensor reduces the current consumption as well as you can complete the measurements faster and take the entire product to sleep mode quickly. Connect this to the 3V3 pin of the Arduino I will brief you about the 4 Pins in the table below: VIN Here you will find the pinouts of the BME280 sensor. BME280 breakout boardīME280 is an 8 Pin IC in a very tiny package. ![]() Normal Mode – Periodically wake up and do measurementsīMP280/BME280 has similar pinouts and can easily be interfaced with an Arduino.Sleep Mode – No operations, lowest power consumption.Or you can communicate with the BME280 sensor via both SPI and I2C communication. The I2C speed of BME280 can be up to 3.4 MHz. You can use I2C to communicate with the sensor. You don’t need any complex circuitry for powering the BME280 sensor. It helps you create weather sensing projects that can find applications in: You can use the sensor to detect room change, measure height, volume, airflow, dryness in the room and more. Let us begin! What Is The BME280 Temperature, Humidity & Pressure Sensor?īME280 is a combined humidity and pressure sensor. You will be able to read the BME280 sensor values using the parts listed above.
